SMUT-MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,319, dated March 8,1898. Application filed August l, 1896. Renewed August 17, 1897. SerialNo. 648,587. (No model.)

To @ZZ whom it may concern,.-

Beit known that I, FAUSTIN PRINZ, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inSmut-Machines; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to smut-machines, and is an improvement on thesmut-machine for which I obtained Letters Patent lof the United StatesApril 3, 1888, No. 380,348.

It has for its object to improve the construction of the cleaning caseor cylinder whereby it may be easily put together and taken apart and becomparatively inexpensive to construct, while at the same time it willbe durable and efcient.

It has further for its object to provide simple and efficient means forsecuring together the adjacent ends of the meeting edges of the metallicplates or bands which constitute the cleaning case or cylinder.

It has further for its object to improve the construction of the beatersby which the descent of the grain between the beaters and side of thecleaning case or cylinder is retarded, so that a better cleaning of thegrain is obtained and breaking of the grain prevented.

To the accomplishment of the foregoing and such other objects as may behereinafter made to appear the invention consists in the constructionand in the combination of parts hereinafter particularly described, andthen sought to be specifically defined by the claims, reference beinghad to the accompanying drawings, forming a part thereof, and in which-Figure 1 is a side elevation of the smut-machine embodying my invention,parts being in section and parts being broken away. Fig. 2 is anenlarged detail showing in vertical section a portion of one of thebeaters, a portion of the cleaning-case, and a portion of one of therings or pans which feeds the grain from beneath one beater to thereceiving-plate of the beater next below; Fig. 3, a side view of severalof the metallic plates used in building the cleaning case or cylinderand showing the straps and couplings joining the ends together. Fig. f1is a plan view of a portion of one set of the beaters; Fig. 5, a sideview of a portion of one of the upright bars placed at intervals aroundthe cleaning case or cylinder and to which the pans are secured. Fig. 6is a vertical section through a portion of one of these upright bars.Fig. 7 is a plan view of one of the segments of one set of beaters. Fig.Sis a side View of the same; Fig. 9, a perspective of two of the platesused in building up the cleaning case or cylinder, and Fig. 10 across-section through the same.

In the drawings the numeral 1 designates the upright legs or supports ofthe machine, of any number desired, which support at the top a ring 2,upon which rests the flange 3 of the top 4. of the cleaning case orcylinder. Between the legs 1 at the bottom is a bridgetree 5, whichsupports the lower end of the rotatable shaft 6, which :may be driven bythe bevel-gears 7 and 8 or otherwise. The shaft 9 of the bevel-gear 8may also carry the fanblades 10, which are employed for creatingair-suction through the flue 11, the drum 12, and the flue 13, so as tocarry o the chaff and other light material from the grain, which will bedischarged from the bottom of the cleaning case or cylinder through aspout 14 into the spout 15,beneath which may be a trough 16 fordirecting the cleaned grain to the point desired. The numeral 17designates a shell or drum which may surround the cleaning case orcylinder. The bottom pan of the cleaning case or cylinder is designatedby the numeral 18 and. may be supported by brackets 19, securedto thelegs or supports of the machine, and from this bottom plate the materialis swept by the bottom set of beaters through a suitable opening intothe spout 14. These parts so far described may be of any approvedpattern and need not be more particularly described, as they do notconstitute my present invention.

The numerals 2O designate a series of upright bars, to the inside facesof which are secured at suitable intervals apart a number of studs orabutments 21, which preferably IOO are made separate from the bars andformed with tenons 22., fitting in openings made in the bars and securedin place by riveting to j a number of metallic plates 25, each platebe-" ing formed on its inside face with transversely-extending cavities26, which will afford good rubbing-surfaces for the grain, and in thebottom of which cavities are formed slots or slits 27, which will permitthe passage of air and of finer particles of dust. These plates areadapted to slide into place between each upper and lower set of studs2l, the faces of these studs preferably being beveled, as shown at 28,and the edges of the plates bearing against the studs correspondinglybeveled, the edges of the plates lying directly back of the pans 24, asindicated clearly in Fig. 2 of the drawings. In this manner ways areformed for the plates, so that they can be pushed or slid into place,the side edge of one plate bearing against the edge of the plate next toit, and so on until the circumference straps assuming a circular form asthey traverse the circumference of the cleaning-case. The two outsideplates are then drawn together by means of couplings, so as to securelybind the band or belt in place. These couplings are formed of slottedangle-plates 32, the lips 33 of which extend at right angles to theslotted portions and are formed with openings for the passage of athreaded bolt 34, one of the openings being screw-threaded, so that byturning the bolts the two lips will be drawn toward each other and theend plates of the series thus drawn together and held by thescrew-bolts. These couplings are applied after the plates have been putinto position. The slotted portions of the angle-plates receive the nuts31, as illustrated in Fig. 3 of the drawings, and these nuts formbearings for the angle-plates to pull on, so that the plates may bedrawn together. It will be observed that one of the slotted angle-platesis longer than the other. The purpose of this is to admit of a moreextended adjustment by leaving a greater space between the lips of thetwo angle-plates. It also permits the angle-plates to be adjusted inposition without extending across the joint between the meeting sideedges of the two end plates, whereby the joint between the plates willconform to the arc of a circle. It is obvious, however, that bothangle-plates might be of the same length, provided that the nuts 31 toone of the end plates were set farther back from the edge of the plate.After one set of the plates has been put into position another set isplaced in position above the first and between the studs which projectfrom the faces of the uprightV bars, and so on until the cleaning caseor cylinder is completed by building up these sections of plates in themanner specified. vThis construction admits of any one set of the platesbeing removed and replaced by another without disturbing the otherplates. It also affords a simple and efcient construction and enablesthe case or cylinder to be built up to the height desired and the partsto be easily assembled in putting the parts of the machine together.

The rotatable shaft 6 carries a series of arms or spiders 35, the hubsof which maybe secured by set-screws or other means to the shaft, sothat the spiders will rotate with the shaft. To the outer ends of thespiders are secured the plates 36, which lie directly below the openingin the return-pans 24, so as to receive the grain from the return-pans.rIo the outer ,edge of the plates 36 are secured the beaters 37. Thesebeaters, plates, and return-pans operate substantially as in my patenthereinbefore referred to. Under the construction specified in thatpatent it was found that the grain would fall in a comparatively thinstream from the pans to the plates and in the space between the beatersand the wall of the cleaning case or cylinder and that some of the grainwould become broken by the force of the blows and the rubbing actionbetween the beaters and the wall of the case or cylinder. For thepurpose of obviating that evil I provide the beaters, preferably attheir lower ends, with laterally-extending lips or shelves 38, each lipor shelf partially filling the space between the adjacent beaters, andwhile permitting the material to drop between the beaters yet at thesame time retarding its flow. These lips or shelves check the falling ofthe grain, so that it falls slower than under other constructions, andalso causes the grain to accumulate to a greater extent in the spacesbetween the beaters and the wall of the cleaning case or cylinder and asthe result breaking of the grain is prevented and a better scouringaction obtained. Each plate 36 is preferably made in sections orsegments, as illustrated in Fig. 7 of the drawings, and a number ofthese sections or segments bolted to the arms or spiders, so as to formthe annular plate. The beaters and their lips or shelves are preferablycast integral withthe loo IIO

sections or segments, and the beaters may be j The grain is fed to themachine through the spout 40, which will deliver the grain to the topplate 41, which will be secured to the rotatable shaft 6, so as torotate therewith. The grain is thrown from this top plate 4lcentrifugally and into the space between the top beaters 37 and the wallof the case carried around and rubbed between them and the wall of thecylinder or case. It then passes down onto the pan 24, through which itpasses onto the plate 36 next below, from which it is throwncentrifugally between the beaters and the wall of the case or cylinder,and so on down the entire series of pans and beaters until it is iinallydischarged through the spout li at the bottom of the case or cylinder.

I have described with particularity the preferred details ofconstruction of each part constituting the present invention; but it isobvious that changes can be made in the details Without departing fromthe essential features of the invention.

A drum or guard 42 is placed to the rear of the beaters and return-pans,so as to prevent the grain from rebounding into the space around therotating shaft. This drum is stationary and supported from the returnplates or pans.

Having described my invention and set forth its merits, what I claimis- 1. In a smut-machine, a cleaning case or cylinder formed of sets ofplates arranged one set above the other, and each set formed of a seriesof plates placed end to end and connected together by straps to form abelt or band adapted to be bent into a curved form to form the wall ofthe case or cylinder, and a series of rotatable beaters within the caseor cylinder, said beaters being provided with laterally-extendin g lips,substantially as and for the purposes described.

2. In a smut-machine, the combination of rotatable beaters, annular pansabove the beaters, a case or cylinder surrounding the pans and beatersand formed of a series of plates placed end to end and arranged oneabove the other and bearing against the outside of the pans, and aseries of rotatable beaters within the case or cylinder, said beatersbeing provided with laterally-extendin g lips, substantially as and forthe purposes described.

3. In a smut-machine, a cleaning case or cylinder formed of a series ofplates placed 5 54 end to end and flexibly connected together to form aband or belt, and a coupling for joining the end plates of the band orbelt, said coupling comprising slotted angle-plates and means fordrawing the angle-plates toward each other, the slotted portions of thecouplings being adapted to receive abutments for the couplings to drawagainst, substantially as and for the purposes described.

4. In a smut-machine, a cleaning case or cylinder formed of a series ofplates placed end to end, iieXible straps connecting the plates togetherand secured thereto by bolts and nuts, and a coupling comprising slottedangle-plates and means for drawing the angleplates toward each other,the slotted portions of the couplings receiving the nuts of adjacent endplates of the series to hold the ends together, substantially as and forthe purposes described.

5. In a smut-machine, the combination with a cleaning case or cylinder,of vertical rotatable beaters located within the case or cylinder, saidbeaters being provided with laterally-extending lips to partially occupythe spaces between the beaters, substantially as and for the purposesdescribed.

6. In a smut-machine, the combination with a cleaning case or cylinder,of rotatable beaters located within the case or cylinder, said beatersconsisting of upright wings having braces extending from one facethereof and lips extending laterally from the wings to partially occupythe spaces between the wings, substantially as and for the purposesdescribed.

7. In a smut-machine, the combination of a cleaning case or cylinder,rotatable plates within the case or cylinder, pans for directing thegrain onto said plates, beaters located between said plates and the wallof the case or cylinder, and lips projecting laterally from 4saidbeaters to partially occupy the spaces between said beaters,substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.
